Only ground- or naval-based units with an Arrow IV launcher may use ADA Missiles to attack any airborne unit within 2 hexes (or 2 ground mapsheets) and no higher than 8 Altitude on the Low Altitude Map. ADA Missiles follow the same rules for standard flak attacks found in Total Warfare but consider attacks within the same hex/mapsheet as short range, 1 hex/mapsheet as medium and 2 hexes/mapsheets as long. Units firing ADA Missiles may make no other secondary attacks against other ground targets.[1]
